On the left side of bitrix, there is a sectioned menu displayed (My Workspace, Company...) a newly invited user does not see the CRM section on this left menu, althought all access permissions have been granted (CRM -> Settings -> Permissions -> Access permissions)

If we type in the url: www.ourdomain.com/crm the user can see all the contents of the CRM module (we therefore assume the access permission works correctly) but as stated before no menu entry on the left is visible.
